Bülletään

The solar activity has been quiet over the past 24 hours. The X-ray flux remains below B-level, and the visible solar disc is spotless. Solar activity is expected to remain at low levels.

No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The solar wind parameters are at nominal values. The wind speed ranged between 390 and 320 km/s. Total interplanetary magnetic field strength was below 4 nT and the southward magnetic component ranged between -3 and 2 nT. Enhancement of the solar wind parameters is expected today due to the influence of the equatorial coronal hole that has reached the central meridian on Jan 9. A negative polarity equatorial coronal hole crossed the central meridian overnight, it might influence the solar wind conditions on Jan 16 and onward.

The geomagnetic conditions were quiet and are expected to remain quiet until the arrival of the coronal hole influences on the solar wind measurements near Earth later today. Possible isolated minor storm conditions may be observed, in particular, if the Bz component stays negative for longer periods.
